摘要Eu2+-doped β-Sialon phosphors with a composition of EuxSi5Al1−xOz+xN8−z−x(x = 0.05, 0.06, 0.07) were synthesized in a new synthetic route using novel raw materials, such as nano-silicon dioxide (SiO2), nano-carbon (C), and aluminum (Al). This is different from the prevailing method using Si3N4, AlN, and Al2O3to obtain β-Sialon phosphors. Compared with the conventional method, lower cost raw materials, simpler pretreatment and a relatively shorter reaction time are achieved. The phosphors show a high purity. All the phosphors exhibit green emission under ultra violet (UV) radiation. A broad band of excitation spectra implies the promising application in UV ray based green light-emitting diode (LED). Chromaticity coordinates of the β-Sialon: Eu2+phosphors demonstrate that it is accessible to obtain different green emissions from single phase of Eu2+-doped β-Sialon through adjusting Eu2O3concentration. Furthermore, the EuxSi5Al1−xO1 + xN7 − x(x = 0.05) shows a better thermal stability than the commercial green-emitting silicate phosphor. These results indicate a promising prospect for this efficient and economic route in preparing β-Sialon: Eu2+phosphors, and the phosphors are a highly promising candidate for LED applications. © 2017, Springer Science+Business Media New York.
